It's outdated and confusing.

For the assign ioctl, it only accepts 3 u64 parameters,
assign:bool to indicate if it's adding or deleting qgroup relationship.
src/dst to specify the qgroupid (u64).

There is no room for path at all.

The qgroupid resolve is done completely in user space.

Feel free to delete the comment.
